Make actionpack instrumentation compatible with TruffleRuby

[plantfansam]

We support TruffleRuby on a best effort basis (see open-telemetry/opentelemetry-ruby#1295). Our actionpack instrumentation does not work properly with TruffleRuby, however.

This ticket will be complete when our CI build successfully runs specs opentelemetry-instrumentation-action_pack.

To run these specs in CI, delete the gem from the TruffleRuby filter stanzas (1, 2) in .github/workflows/ci.yml.

The issue looks to be with Bundler, and here's the failure from a CI run when running bundle exec appraisal install (it's specifically failing to run bundle install on the Rails 6.0 version):

I'm having a hard time debugging/recreating the issue locally to figure out what specific reason bundler is failing, but I'll keep playing with it.
